Write an equation for slope intercept.. y intercept is 9. X intercept is 3

The equation for the slope-intercept form is:

y = mx + b

Given that the y-intercept is 9, the equation becomes:

y = mx + 9

Given that the x-intercept is 3, we can derive the slope:

3 = m(0) + 9
3 = 9
m = -3

Therefore, the equation becomes:

y = -3x + 9
